The answer is D, 1000pi
Use SA=2πrh+2πr^2.
Plug in the numbers A=2π*10*40+2*π*10^2.
and you get <span>3141.59.
divide by Pi and you get 1000</span>
Answer: $0.35 which is the same as 35 cents
==========================================
Work Shown:
3 cookies = $1.05
3/3 cookies = $1.05/3
1 cookie = $0.35 = 35 cents
Triangle Area = .5 * (base * height)
36 = (base * height) / 2
So let's say base = 9 height 8
If base and height are scaled by a factor if 5 than
base = 45 height 40 and
area = .5 * (45 * 40)
area = 900
Basically, the area increases by a factor of 25.
The base increases by 5 and the height increases by 5 so the area increases by 5*5 = 25
Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = 
r³
Plug in the volume and solve for r, the radius:
V = 
r³
7961 = 
r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
